Passive Component Models for GaAs MMICs
-
Abstract
Various GaAs MMIC (monolithic microwave integrated circuit) passive components,including rectangle spiral inductors,MIM capacitors,and film resistors,are fabricated,and their equivalent circuit models are established.Various polynomial formulas are introduced to characterize models and performances of different passive components.This is convenient for circuit design.The extracted capacitance per unit area of the MIM capacitors is about 195pF/mm2,and the sheet resistance of the NiCr film resistors is about 16.1Ω/□.The effects of the geometrical parameters on the spiral inductors are also analyzed,and the results show that reducing the parasitic losses of the inductor areas helps to obtain high quality inductors. -
